Definitions

  • the present invention relates to a method for determining the configuration of a danger warning system comprising a central station and appliances connected thereto via a signal line, in which danger warning system each appliance has an isolator switch, a unique identification number and a communication address, and the appliances, disconnectable via the isolator switches, can be started sequentially.
  • appliances should be understood to mean, in particular, hazard detectors, but they may also be actuators, such as optical or acoustic alarm transmitters, relays, alarm displays, transmission appliances for transmitting alarms and the like.
  • actuators such as optical or acoustic alarm transmitters, relays, alarm displays, transmission appliances for transmitting alarms and the like.
  • EP-A-0 485 878 describes a method for determining the configuration of detectors of a danger warning system in which, prior to allocating the communication address to the detectors, the central station must perform a large number of steps, which demands a relatively large amount of time. Determination of the position of a newly-installed detector by restarting the whole system is time-consuming, especially with relatively large networks, and certainly is not efficient. Apart from that, this method does not function with symmetrical branches.
  • EP-A-0 880 117 describes a method for automatically locating detectors in which the detectors are equipped with means for communicating with neighboring detectors. To locate a detector, all the detectors open their disconnectors and the detector to be located transmits a corresponding message which is received only by its neighbors. The disconnectors are then closed and it is determined which detectors these neighbors are, enabling unambiguous determination of the position of the detector which is to be located. This method is relatively fast, but requires all detectors to be equipped with the communication means mentioned.
  • the inventors propose that, upon starting, the appliances log on sequentially to the central station and, in the event of simultaneous logging-on of more the one appliance, only the logging-on of one of these appliances is accepted.
  • a first preferred embodiment is characterized in that the appliances log on to the central station with their communication address, and in that, in the event of simultaneous logging-on by appliances with different communication addresses, the communication addresses are distinguished by an arbitration method and the two different communication addresses are sequentially registered.
  • a second preferred embodiment of the method is characterized in that the appliances log on to the central station with their communication address, and in that, in the event of simultaneous logging-on by appliances with identical communication addresses, the collision of these identical communication addresses is identified and resolved.
  • a third preferred embodiment of the method is characterized in that the appliances log on to the central station with their identification numbers, and in that sequential logging-on is ensured by an arbitration procedure via the identification number and a unique communication address is allocated to the appliances via the identification number.
  • a first alternative method of achieving the object is characterized in that, upon starting, the communication addresses of all appliances are polled by the central station and newly-added communication addresses are thereby identified, and in that, in the event of multiple occupancy of communication addresses, the collision of these identical communication addresses is identified and resolved.
  • a second alternative method of achieving the object is characterized in that, upon starting, the identification numbers of the newly-started appliances are polled by the central station and a unique communication address is allocated to each appliance found.
  • the inventors further propose a danger warning system with a program-controlled central station to which a plurality of appliances are connected in parallel via a signal line, each of which appliances includes at least a sensor, an isolator switch, evaluation electronics with at least a memory and an individual and unalterable serial number allocated by the manufacturer.
  • the danger warning system is characterized in that the central station includes units to execute the process steps mentioned.
  • a preferred embodiment of the danger warning system is characterized in that the appliances mentioned are formed by hazard detectors and/or actuators, such as optical or acoustic alarm transmitters, and/or relays and/or alarm displays and/or transmission appliances for transmitting alarms.
  • hazard detectors and/or actuators such as optical or acoustic alarm transmitters, and/or relays and/or alarm displays and/or transmission appliances for transmitting alarms.
  • FIG. 1 is a schematic representation of a danger warning system
  • FIG. 2 is a flow chart to clarify the determination of the configuration of a line network.
  • the danger warning system represented in FIG. 1 includes of a central station Z, a ring-shaped signal line ML starting from said central station Z with detectors M 1 , M 2 and M 5 to M 10 connected to said signal line ML, and a stub line SL branching from the signal line ML with detectors M 3 and M 4 connected thereto.
  • the detector M 1 have the communication address 1
  • the detector M 2 have the communication address 2
  • Each of the detectors M n includes at least one sensor for a hazard criterion, such as smoke, temperature or a flammable gas, evaluation electronics (both not shown) and an isolator switch S.
  • each detector M r has a communication address and a unique identification number.
  • the latter has been allocated to the respective detector by the manufacturer; it is unalterable and occurs precisely once.
  • a detector M should be understood to mean not only a hazard detector but quite generally an addressable appliance installed in a signal line. Apart from a hazard detector, this may be an actuator, such as an optical or acoustic alarm transmitter, a relay, an alarm display, a transmission appliance for transmitting alarms, and the like.
  • an actuator such as an optical or acoustic alarm transmitter, a relay, an alarm display, a transmission appliance for transmitting alarms, and the like.
  • the detectors M n which are disconnectable via the isolator switches S, are started sequentially by the central station Z, a unique communication address being optionally allocated to the detectors.
  • information from the detectors M n if present, such as detector type, an identification number such as a serial number or an existing communication address, can be read into the central station Z for complete determination of the configuration of the detectors on the network.
  • the central station Z waits until no more detectors M r , log on, and then also knows how many detectors are connected directly behind the one which last closed its isolator switch S. If only one detector has logged on after the last closing of an isolator switch S, no branch is present; if two detectors have logged on there is a single branch, and so on.
  • the detectors transmit their communication addresses to the central station Z, which, upon receiving two or more communication addresses simultaneously, prevents the simultaneous logging-on of a plurality of detectors with different communication addresses by an arbitration procedure.
  • the addresses are compared bitwise and the detector which has one bit set, for example, is preferred.
  • This detector then receives a command from the central station Z and closes its isolator switch. Then the communication address of the detector not preferred in the arbitration is read into the central station Z; the detector receives a command from the central station Z and closes its isolator switch S. Then the next detector logs on, and so on.
  • the detectors transmit their communication addresses to the central station Z, which identifies the simultaneous arrival of two identical communication addresses as a collision and resolves the collision.
  • the resolution is effected in that the central station Z allocates an invalid communication address to all the detectors involved in the collision, whereupon the detectors with an invalid communication address log on again according to variant 3 ( FIG. 2 ).
  • the detectors log on to the central station Z with their identification number. Sequential logging-on is ensured by an arbitration procedure of the type described and unique communication addresses are allocated to the detectors via the identification numbers.
  • the communication addresses of all detectors are polled by the central station Z, whereby newly-added detectors are identified. Multiple occupancy of communication addresses is identified as a collision and the collision is resolved in the manner already described.
  • the identification numbers of the newly-started detectors are polled by the central station Z (in practice not all possible identification numbers can be polled, because the time required for a large number of multidigit identification numbers would be too long), a method based on a binary search tree being appropriate. A unique communication address is then allocated to each detector found. ,
  • the isolator switches S of all the detectors M n are opened.
  • the detector M 1 for example, then logs on to the central station Z with its communication address 1 , the central station sends the detector M 1 a command to close its isolator switch S and waits for the next detector M 2 to log on, which logging-on takes place analogously.
  • the two detectors M 3 and M 5 send their respective communication addresses 3 and 5 to the central station Z.
  • the central station registers that a branch must be present and also registers that two detectors with different communication addresses are logging on simultaneously, and applies the arbitration procedure described under point 1 , in which the detector M 3 , for example, is preferred.
  • the detector M 4 logs on to the central station Z, then the detector M 5 , etc.
  • the central station Z now knows the configuration of the network of the fire danger warning system. If, for example, because of an exchange of a detector during maintenance/revision work, the detector M 8 had the communication address 3 , the central station Z would identify when that detector logged on that the communication address 3 was already allocated to the detector M 3 , and would readdress the detector M 8 with a free communication address.
  • a limb of a branch may itself contain a branch.
